SAMUEL F. HUGHES, OF FORT MADISON, IOWA.

TREADLE GUIDE FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 678,736, dated July 16,1901. Application filed February 27, 1901. Serial No. 49,084. (Nomodel.)

To all whom it may concern:

Be it known that I, SAMUEL F. HUGHES, a citizen of the United States,residing at Fort Madison, in the county of Lee and State of Iowa, haveinvented certain new and useful Improvements in Treadle-Guides forCultivators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to treadles-guides for cultivator-s, moreparticularly to devices applicable to straddle-row cultivators by meansof which the gangs of plows may be moved to either side of the directline in which they would normally travel as the machine is drawn along.

The object of my invention is to improve and simplify the arrangementand formation of the various parts of a device for accomplishing thesidewise movement mentioned and to place the treadle and other mechanismimmediately related thereto in the most convenient operative positions.

Each constituent element of my invention is described in detail and itsindividual office, together with the mode of operation of the whole,fully explained hereinafter.

Of the accompanying drawings, throughout which like numerals designatelike parts, Figure 1 represents a rear view of certain portions of astraddle-row cultivator of usual construction, showing my inventionapplied thereto and exhibiting its position with respect to thoseportions. Fig. 2 represents a modified form of my invention detached,and

Fig. 3 is an enlarged side view of the gearing and attachments shown inFig. 1.

Considering the drawings, numerals 1 and 2 mark the wheels of acultivator.

3 designates the arched axle; 4, the frame supported by the axle; 5 and6, the pivoted arms or booms arising from the frame of the machine, andnumerals 7 and 8 mark the hanging standards or rods pivotally suspendedfrom the upper ends of the pivoted arms 5 and 6. The office of thehanging rods is to support the plow-beams 9 and 10. Each rod has at itslower extremity a pivotal conferred to by number 41.

the foot in foothold would draw upon chain and the cars 15 and 16 uponbeam 10. Bolts l7 and 18 pivotally couple the prongs and ears, as shown,and the plowbeams are thus joined to the hanging rods and maybe raisedby them in the ordinary manner when desired.

The preferred form of my invention is illustrated in Fig. 1. Abouthanging rod 7 is a collar 19, held in place upon the rod by asetsorew20. Inclosing the rod, immediately beneath collar 19, is the hubof a segmental gear 21, and projecting from the hub is an arm 22,provided at its outer end usually with an eye or hook. Next beneath thehub of gear 21 is the sleeve 23, the position of which is fixed upon therod by the set-screws 24 25, and passing through the sleeve and rod isthe pin 26, which forms a bearing for the foot-lever 27. At the upperend the lever possesses the geared are 28 and at the lower end thetreadle or foothold 29. The eye or hook at the end of the arm 22 isconnected with the bend of the axle, as shown, by a rod or chain 30. If,therefore, the foot of the lever be forced forward, the interposedgearing causes the arm 22 to draw upon the chain, which results indirecting the movement of hanging rod 7, and consequently the beam 9 andits gang of plows, to the left.

The hanging rod 8 carries duplicates of the geared and connected partsjust described above. The collar is marked 31, the setscrew 32, thegeared segment 33, its projecting arm 34:, the sleeve 35, the set-screwsby which it is secured to the rod 36 and 37, and the transverse pin 38.The foot-lever bears the referencenumber 39, its toothed arc meshingwith the geared segment numbered 40, and at its lower end the footholdis re- A forward push of 42, connecting-arm 34, and the bend of theaxle, and the hanging rod 8, with the beam 10 and its gang of plows,will move to the right.

In Fig. 1 it will be noted that a chain 43 joins the hanging rodsusually, but not necessarily, above the collars 19 and 31. It istherefore evident that the hanging rods and their attached plows mustboth move toward the same side. When the treadle on the right isoperated, the plows move to the right, and they are brought back intothe normal middle position or moved to the left by the treadle upon theleft side.

Fig. 3 more clearly illustrates the gearing upon the left of Fig. 1, andas both sets of gears are alike this figure may be regarded asillustrating either set.

It is often desirable to accomplish the sidewise movement sought by amodification of my invention shown in Fig. 2. A foot-lever 44 extendshorizontally upon the right side of the hanging rod from a hub 45encircling the rod. A coupling 46 keeps the hub from sliding down therod. At right angles to lever 44 an arm 47 projects from the hub, and arod 48 connects the end of the arm and the bend of axle 3, as before.The rod 48 is substituted for the usual chain connections when it isdesired to operate the gangs independently, each hanging rod beingsimilarly equipped with a foot-lever, hub, arm, and rod, as stated. Itwill be noted that the hanging rod 49 used with this modification has anoutward bend 50 and a vertical portion below the bend. The companion rodin a cultivator would possess a like bend extending in the oppositedirection. The bent rods bring the footholds in convenient position forthe rider.

In Fig. 2 the connection with the plowbeam 9 is also of modified formand is in the nature of a universal joint. Coupling 46 is an L-shapedpiece or casting and has secured to it and projecting at right angleswith the hanging rod a short rod 51 of about the same size as the otherrods, and the short rod 51 passes through the tubular portion of aconnection 52 and is retained by a cotter 53. The connection 52 ismovable upon rod 51, and it has two downwardly-extending sides 54 and55, which straddle a cross-brace 57 of plow-beam 9, and the sides arepivotally secured to the brace by the bolt 58. In this construction theplows are permitted to adjust themselves to all inequalities of level ofthe ground. Thus the tubular portion encircling the rod 51 allowsthefront or rear of the beam to rise or fall, and the pivot-bolt 58,through the sides 54 and 55, makes it possible for either side of thebeam to tilt when necessary.

I am aware that there are a number of treadle-guides constructed andused, and I do not claim a device broadly for that purpose.

What I claim, and seek to secure by Letters Patent of the United States,is-

1. In a treadle-guide for cultivators, the combination of the hangingrods, plow-beams pivotally coupled to said rods, foot-levers pivotallysupported upon the said rods, and devices connecting the saidfoot-levers and relatively fixed portions of the cultivator whereby thesaid rods and beams may be moved toward the sides, substantially asdescribed.

2. In a treadle-guide for cultivators, the combination of thehangingrods, plow-beams pivotallyfcoupled to said rods, foot-leverspivotally supported upon the said rods, the said foot-levers havinggeared portions, geared segments having hubs pivotally supported uponthe said rods, the said segments meshing with the geared portions of thesaid foot-- levers, and devices connecting the hubs of the said segmentsand relatively fixed portions of the cultivator whereby the said rodsand beams may be moved toward the sides, substantially as described.

3. In a treadle-guide for cultivators,-the combination of the hangingrods, plow-beams pivotally connected to said rods, foot-levers pivotallysupported upon the said rods, the said foot-levers having gearedportions, geared segments having hubs pivotally supported by the saidrods, the said segments meshing with the geared portions of the saidfoot-levers, arms projecting from the hubs of the said segments,andconnections between'the said arms and relatively fixed portions of thecultivator whereby the said rods may be moved toward the sides,substantially as described.

4. In a treadle-guide for cultivators, the combination of the hangingrods having lateral bends and vertical portions below the said bends,plow-beams pivotally joined to the lower ends of the said rods,foot-levers having hubs pivotally supported upon the said verticalportions of the rods below the bends, and connections between the saidhubs and relatively fixed portions of the cultivator whereby the saidhanging rods and plow beams may be moved toward the sides, substantiallyas described.
